In terms of Lewis Acid-Base reaction between Fe^+3 and OH^-: FeCl_3 + 6H_2O doub

Question

In terms of Lewis Acid-Base reaction between Fe^+3 and OH^-: FeCl_3 + 6H_2O doubleheadarrow [Fe(OH)_6]^-3 + 3HCl FeCl_3 is the Lewis acid the coordination number and oxidation number, respectively, of the transition metal in the coordination compound [Cr(en)_2Br_2] NO_3 are 4, 3 a complex with a formula [ML_4]^2+ shown splitting energy; Delta = 3.46 times 10^-10 J, the color of the complex is Yellow the correct formula of the compound: Potassium aquapentacyanoNicklate(II) is: K_2[Ni(CN)_5(H_2O)] The model accounts for the magnetism and color of coordination compounds is the VSEPR theory model.

Explanation / Answer

1. True

Lewis Acid accepts electron

2. False

Coordination number - 6

Oxidation number : x - 2 = -1 => x = +1

3. true

e = hc/

Calculating approximately equals 574nm

Hence Yellow colour

4. true
